APPARATUS FOR MAKING STEEL.

SPECIFICATION forming part of Letters Patent No. 340,000, dated April 13, i886.

tNoinodei.)

To oziZZv whom it may concern.-

Be it known that I, EZRA NIoiIoLsoN, of Cleveland, in the county ot' Cuyahoga and Siate ot' Ohio, have invented certain new and useful Improvements in Apparatus for Making Steel, of which the following is a specification.

This invention is an improvement in appa.- ratus used in the Bessemer process.

In consists in the combination ot' the pipe through which the air is forced with a second pipe pivoted thereto, a dip-pipe attached to the latter, a receptacle for niolten liquid,which receives said dip-pipe, and a joint between the two pipes first mentioned, which consists of a tapering elbow and a sleeve having corresponding internal shape. the construction of said elbow and sleeve allowing the rotary movement ot' the pivoted pipe, and also allowing said parts ot' the joints to be adjusted telescopic-ally in compensating for wear.

In the drawings, Figure l is a pian view of the apparatus with the joint in section. Fig. 2 is a side elevation with the portable vessel and tire clay end ot dippipe in section. Fig. 3 represents a vertical section oi' the dip-pipe, showing its const ructiou, on an enlarged scale.

A is a common iron pipe connected to a. pipe, A', leading from an air compressor or a blower by a joint, enabling it to be raised at its opposite end. Said joint consists of' an elbow, B, having a tapering end, B', and provided with a flange. b. Said taper is fitted to turn in a sleeve, C, to which the pipe A is attached. It has a iiange, c, at each end. Suid sleeve is held in position by wings l) l), resting against the llangcs b and c and bolted together with bolts rl d. Iith this construction oftapering joint the wear and loosening which may take place may readily be reniedied by tightening np the bolts.

G isa tire-clay pipe,in the upperpart of which is Iitted and secnrd an iron pipe, H, having :in annular flange, h. The base ofthe upper portion ofthe pipe G is enlarged to receive the iron pipe, which is secured therein by filling in the space around the iron pipe down to the flange with plastic material. The upper end of pipe H projects above the clay-pipe, and is screw-threaded, for the purpose of attaching it to the cover I of the vessel J.

The cover I consists of semi-spherical hood, which maybe of eastfirou, provided with a. screw-tlireaded neck, i', into which the aforesaid pipe II is screwed. Said cover also has a boss or elbow, k, for attaching it to the pipe A. The hood I is provided with an annular tlange at its lower edge, which holds a fireclay lining, and is also provided with a fireclay-Iined tube, L, i'or the llames, Ste., to escape during the process of' blowing.

M is :i portable vessel consisting ot' au iron slieil lined with Iire'cluy, and may be mounted on a truck, N, for moving it about, and is also provided with trunnions T, for the purpose of lil'ting it with a crane, ii' desired.

For raising the dip-pipe and the cover, a rope or chain is attached to a ring, O, on the boss k, and passes over a pulley overhead, and having a couuterbalancc weight, `\V. This enables the pipe and cover to be raised with ease t'or clearing the pipe from the vessel for removing it from under said pipe, as seen in dotted lines in Fig. 2.

I ain aware that it is not new to combine a pivoted blast'pipc having a dip-pipe and cap attached thereto with a receptacle for molten metal, which is covered by said cap, and into which said di ppipe extends. I ain also aware that it is not new to provide such a pivoted pipe, thus combined, with a. counterbnlanccweight. I ain further aware that ajoint coinposed of a tapering pipe anda correspondingly-shaped siceve is not broadly new. Ido not claitn, broadly, any otsuch constructions; but,

Havingdescribed my invention, Iclaiin In combination with pipes A, A', and II and vessel J, arranged as described, the tapering elbow B, which is attached to pipe A and free to turn therewith, and the sleeve C, having a corresponding internal taper and attached to pipe A', said parts B O constituting a joint which allows turning, and also telescopic adjustment to compensate i'or wear, substantially as set iorth.
